This is a random fanfiction idea I had while reading the LOTM novel. What if there were a complete pathway for magic, and what would it look like? So, I decided to use a famous series famous for its magical world and possibility. The Harry Potter world, as a starting point and later add different worlds as the story progresses.
As you have read in the synopsis, the story focuses on the character Scarlet, who initially decides to use the scraps of meta knowledge she remembers to learn magic early and determine whether to stay or leave the wizarding world after her O.W.L. exams. However, everything changes in her third year when, she decides to open and read the diary of Rowena Ravenclaw that she had found in the Room of Requirements after her question of "what is pinnacle of magic?"
The diary describes how Rowena attempted to see the pinnacle of magic and, with help from Salazar, devised the ritual recorded in the book, which, once performed, allows users to see the pinnacle of magic.
The book also explains how seeing the pinnacle of magic—and realizing that other worlds exist with magic stronger than theirs—shook her and Salazar to their core. Seeing the mention of other worlds, Scarlet considers using the ritual, but uncertainty grabs hold of her as to what would she do with such knowledge?
After performing the ritual, she encounters an unexpected result: she cannot remember what happened after initiating it. All she knows is that an exquisite tattoo now appears on her left hand—a card depicting a woman made of starlight, with mysterious connected runes etched across her body as if making a living spell equation. She wore a dress designed from countless spell circles. (AN: Look up Agatha Harkness from Marvel What If...? for the visual idea.) On the floor beside her is a slowly fading message etched into the stone: "What is life without any risk? Reach sequence 2 to know what happened here, or... continue your ordinary... mundane...caged life, same as last one."
